Yoda is my Father, yes but this is no ordinary city. And the Emperor's tower is no ordinary tower. It reaches up into the lower atmosphere. Plus, if that part of the city is at night, you could use some of those night shots on Coruscant that adorn all three PT movies.

Also, what will the rebel fighters do once Han does get the shield down? What are they attacking?

The Death Star.

Here's what I'm saying:

You move the location of both Endor and the DS to the Galactic Core. Make Endor a moon of Coruscant. Have the shield protecting the DS just like ROTJ does. So, the rebels would be going to destroy the DS in the heart of the Empire in a desperate attempt to end the war once and for all.

This could make for a great crawl.

Something like: in a desperate attempt to end the war once and for all, the rebels gather all available ships and troops for an assualt into the heart of the empire, where the death star, and the emperor, lye in wait.
